Abstract
An image forming apparatus includes a feeder for feeding a new paper accommodated in a feeding cassette, an image forming device which forms an image on the paper fed by the feeder, an intermediate container which temporarily accommodates the paper fed by the feeder and having the image thereon, a refeeder which refeeds the accommodated paper from the intermediate container to form an image on the paper again, a detector which detects presence or absence of paper to be fed by the refeeder for image formation, and a controller which effects a change-over from the paper feeding operation by the refeeder to the paper feeding operation by the feeder when the detector detects the absence of paper to be refed or forbids the paper feeding operation by the refeeder until the detector detects the absence of paper to be refed after the paper has been accommodated in the intermediate container.
